Description Christophe Marin 2008-04-18 16:36:29 UTC

Version:           4.00.69 (KDE 4.0.69 >= 20080410) (using 4.00.70 (KDE 4.0.70 >= 20080418), compiled sources)
Compiler:          gcc
OS:                Linux (i686) release 2.6.24-16-generic

This is a severe issue due to KDE updating config files *after* applications are closed.

Testcase (trying to reproduce it is not advised)

- Open a KDE session,
- Open KDE applications
- Fill your home partition 
- Close your KDE apps (or logout)

=> Look in $KDEHOME/.kde/share/config, the applications you opened while the partition was full now have a zero size. All settings were lost.

Changed severity to "GRAVE".

Comment 2 Elias Probst 2008-06-16 13:45:35 UTC

I can confirm this.
KConfig needs to check first whether there is space left on the volume - if not, don't do anything, just leave the files in their previous state and if possible, raise a warning.

Raising priority to VHI. 

This issue needs some attention before 4.1 comes out. Otherwise, change it back to normal.

Comment 5 FiNeX 2008-06-18 13:06:58 UTC

It should be fixed, togheter with the "free space" login issue.

Comment 6 DjDarkman 2008-06-19 07:10:14 UTC

I would recommend:
- checking of disk space
- try to write to a temporary file (in the same directory)
- if successfull then swap the two files
- if not successfull warn the user of the problem more specificly ("can`t save this or that" doesn`t tell the problem)

and I would recommend to offer a possibility to save/export this data to a user specified location so that the user doesn`t loose it`s data like did.

SVN commit 825453 by lunakl:

Check whether closing the file was actually successful, otherwise
this code happily overwrites original files with empty ones. Also
remove the right (temporary) file on failures.
